The Big Stick Policy is a diplomatic strategy developed by President Theodore Roosevelt, emphasizing the use of military force as a means to achieve foreign policy goals, particularly in Latin America. This approach was rooted in the belief that displaying military strength would deter aggression and promote U.S. interests abroad, while also allowing for negotiations backed by the threat of force. It was most prominently applied during Roosevelt's presidency in the early 20th century, shaping U.S.-Latin American relations through interventions and assertive diplomacy.
